The best start was for Grohs, sharing a 935 with Olympic champion Bruce Jenner, but after a puncture Fitzpatrick took over, followed by Ongais and the two Lancias. When Ongais went by Fitzpatrick, who slowly lost a cylinder the MoMo Porsche of Jöst and Moretti blew up. Then the rain fell and flooded the track, and the race was stopped while the Lancias were in front now. It stayed that way, Heyer and Patrese winning, Cheever/Alboreto second and the first Porsche, that of Fitzpatrick and Redman third.
